Title: Data stream encoding where encoding technique selected according to available power
Inventor: GARG SHASHANK
IPC: H04N19/50
Filed: 2009-11-20
Abstract: An indication of an amount of available power is received 512, 513, 514 from a power management module 510 (180, fig. 1). A digital data stream is encoded by an encoder (140, fig. 1) using a first encoding technique if the amount is above a given threshold or else using a second encoding technique if the amount is equal to or below the threshold. The first encoding technique may require more power than the second encoding technique. The selected technique may represent video image quality, for example, where higher quality video 520, 530 requires more power than lower quality video 540, 550. The available power may be indicated for a sequence of amounts at corresponding time instances, the encoding technique being dynamically selected according to the amount of power available at a given instance of time. The encoding techniques may be implemented by corresponding logic blocks in the encoder, those blocks not required at any time being switched off.

Title: Sheet metal blanking and shearing machine
IPC: B21D43/02
Filed: 1971-04-20
Abstract: 1341733 Shearing ENGEL INDUSTRIES Inc 20 April 1971 [24 June 1970] 10075/71 Heading B3W For shearing a workpiece from strip metal and notching the edges at predetermined positions j, strip 15 is fed by rollers 19, 20 which also level it past a length measuring roller 29 and pulse generator 28 to a first notching station where dies 35, one at each end of an eccentrically driven ram 34, form notches j. A second, similarly driven ram 48 may be provided for punching notches k where the workpiece is to be folded to form, e.g. a duct. A more powerful ram 52 carries a shear blade (not shown). A length counter 10 connected to the pulse generator 28 starts counting pulses when the leading edge of the strip passes a position on the machine bed 36, conveniently at the ram 34, which corresponds to a leading edge datum d of the workpiece. The counter 10 is set to length f and when the ram 34 has punched the first pair of end notches j the counter re-sets itself to length f. At the end of the count the strip feed is slowed and stopped, the ram 34 is actuated and a tracking counter 65 is gated on which counts a fixed number of pulses corresponding to the linear spacing between ram 34 and shear ram 52. At the end of the fixed count, the feed is slowed and stopped and the ram 52 is actuated to shear the strip transversely between notches j. The counter 65 is gated off until the counter 10 reaches zero again. At each re-setting of counter 10 a counter 11 begins counting. The counter 11 has three settings corresponding to spacings p, q, and r respectively between pairs of notches k. When the p count is reached, a tracking counter 69 is gated on which has a fixed count corresponding to the linear distance between the rams 34 and 48. When the fixed count is reached the feed is slowed and stopped, the ram 48 is actuated to form notches k, the counter 11 re-sets itself to the spacing q and a tracking counter 70 is gated on. Notches k are formed and a similar sequence bringing in a tracking counter 71 leads to the punching of notches k at spacing t. At the end of the count corresponding to spacing t, the counter 11 stops counting and is re-set when the counter 10 re-sets itself. Time delay circuits such as 63 ensure that the rams have moved out of the feed path before feeding is re-started. The drive to the rams 34, 48 and 52 include one-revolution clutches 42, 50 and 57 respectively.

Patent GB-376807-A (GB)
Title: Improvements in and relating to the production of artificial resins and products therefrom
IPC: C08G12/12
Filed: 1931-04-08
Abstract: Artificial resins are prepared by condensing urea with aqueous formaldehyde in the molecular proportions of 1 : 1,05-1,55 at a temperature not exceeding 30 DEG  C. and using a pH of 4-7, and then evaporating the product to substantial dryness at a temperature not exceeding 60 DEG  C., e.g. by spraying into a current of warm air. For adjusting the acidity, triethanolamine, guanidine, and other organic bases are preferably added to commercial formaldehyde, but potassium and sodium hydroxides may also be used.  The dried material, alone or mixed with fillers, may be moulded under heat and pressure to give shaped articles, e.g. lenses; it may also be dissolved in water to give a varnish or lacquer, or mixed with pigments to give a cold water paint.  The solution prior to evaporation may be used for impregnating paper or fabric which is then dried at a low temperature; sheets of this material may be superimposed and hot pressed to form a laminated product.  A filler, such as wood flour, blanc fixe, sulphite pulp or a powdered urea-formaldehyde condensation product, may be added prior to or after the evaporation; plasticizers such as resins or castor oil may also be admixed with the dried material.  Addition p  of the resin known under the registered Trade Mark of " Glyptal " is useful when it contains free phthalic anhydride, which increases the acidity of the moulding mixture; b -bromcinnamic acid and its salts are useful for the same purpose.  An example is given of the condensation of urea with formalin solution whose acidity has been reduced to a pH value of 6 by addition of triethanolamine; the temperature is maintained at 30 DEG  C. by the use of coils in the reaction vessel through which first warm water and then cold water is passed; after two hours the solution is filtered and allowed to stand a further 11-14 hours; sulphite pulp is added, the mixture dried in an air drier at ordinary temperature, and finally ground in a ball mill. Specification 373,184 is referred to.ALSO:Compositions are prepared by incorporating a filler with a condensation product obtained by heating urea with aqueous formaldehyde in the molecular proportions of 1 : 1,05-1,55 to a temperature not exceeding 30 DEG  C., using a pH of 4-7 and evaporating the product to substantial dryness at a temperature not exceeding 60 DEG  C.
